A Unique Best Friends Necklace

My mother bought two of these necklaces for me and my best friend my Freshman year in High School. My friends said "Friends Forever" mine (pictured below) says "Best Friends". I have had it for 10 years now and there was a time when I wore it every day. So as you can see it is very scratched up.
I would love to find another one. One that says love or something like that. Unfortunately my mother does not remember where she got it. I tried searching online with no luck. So, I am on a quest and thought maybe someone will read this and can tell me where I can buy another one.

When it spins the two sides mesh together to read "Best Friends"
